snon JACK.

Application filed October 7, r1922. Serial No. 553,147.

State of Ohio, have invented certain new` and useful Improvements in Shoe Jacks, of which the following isa specification.

This invention relates to Certain new and useful improvements in shoe jacks and has particular reference to a stand carrying a cross head for supporting shoe lasts that are capable of being shifted to various positions to facilitate operation upon a shoe supported on the last.

The primary object of the invention resides in the provision o-f a shoe jack that is vertically adjustable to permit a person to use the same while either sitting or standing.

A further object of the invention is to provide a shoe jack embodying a standard supporting a forked head, each Vend of which is fashioned for vertically and horizontally supporting a last supporting block to facilita-te convenient operation upon a shoe.

A still further object of the invention resides in the provision of a shoe jack of the type above set forth wherein a bracket arm is positioned between the toe portion of a shoe last and the adjacent end of the forked head for rigidly supporting the toe portion of the last while working thereon while an adjustable strap may extend from the jack stand and the shoe last or the shoe last and the adjacent portion of the forked head.

The invention further embodies detail improvements in a shoe jack of the type above set forth, such as devices for anchoring the shoe last to the jack and other adjustable devices.

With the above general objects in View and others that will appear as the nature of the invention is'better understood, the same consists of the novel form, combination and arrangement offparts hereinafter more fully described,shown inthe accompanying drawings and claimed. Y

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a shoe .jack constructed in accordance with the ypresent invention showing the forked liead supported on the jack standard Aand the removable section of the jack standardV for varying the height of the forked head,

Figure/2 is a side elevational view of the jack, partly in section showing the manner of mounting one. of the last supporting blocks in the forked head, I

`Figure 3 is a fragmentary detail sectional view showing the last' mounted upon the block and anchored to the forkliead,

Figure 4 is a detail sectional view taken on line'gIV-IV of Fig. 1 showing the last vertically supported upon the upper end of the forked head,

Figure 5 is a fragmentary detail sectional view showing one end of the forked head laterally shifted to permit rotatableadj ustment thereof, f

`Figure 6 is a detail sectional View taken t on line VI--VI of Fig. 5, and

Figure 7 is a detail sectional view taken on line VII- VII o-f Fig. l showing the adjustment for the strap that anchors the shoe last to the vertical standard.

Referring more in detail to the accompanying drawings there is illustrated a shoe jack embodying a standard including a base portion 1 having a post 2 detachably mounted thereon, the upper end of the post supporting a forked or cross head 3 having perpendicularly extending end portions 4 shown more clearly in Fig. 1.y

Each end portion 4 of the cross head 3 carries a pivotally mounted hinge 5 hinged upon the horizontal pins 6 shown more clearly in Figs. 2 and 5, the pins 6 being laterally positioned relative to the end portion 4 of the cross head, one side of the pivoted head 5 being cut away as at 7 to constitute a seat for the p-ivotally mounted locking plate 8 for retaining the pivotedhead 5 perpendicularly positioned'as shown in Fig. 1. The head 5 supports a block 9, the head 5 being provided with a longitudinally extending bore 10 to accommodater the passage of the screw bolts 11 rformed integral with the block 9 as shown in Fig. 5, the inner end of the screw bolt 11 having a nut.12 threaded thereon that is operated by the key 13, access to the nuts 12 being obtained when the head 5 is pivotally shifted to the position shown in Fig. 5. It is to be understood .that the block 9 may be rotatably adjusted relative to the head 5 and cross head 3, the adjacent faces of the end portion 4 of the cross head, and the pivotally mounted head 5 being out away to provide a clearance for the nuts 1,2.

The block 9 is enlarged at its upper end and is fashioned to carry a laterally or vertically positionedhshoe last, the upper' end of the block adjacent one edge tliereofbeing provided with a perpendicular threaded bore 14 communicating with an enlarged pocket4 15 opening at each side of the head 9 as shown in Figs. 1 and 4. The last 16 carries a screw bolt 17 projecting from the ankle portion thereof and freely yextends through the spacing member 18 that carries 'at the lower end thereof an externally threaded operable from opposite sides of the block 9 as will be readilykunderstood froman inspection of Figs. 1 and 4 ofthe drawing. The outer end of the block 9 is also provided with a transverse internally lthreaded bore 21 within which the threadedextension 419 of the spacing ymember 1S may be positioned as shown in Fig.'3, thejscrew bolt 17 carried by the last 16 freelyextending through the spacing member and its extension to be engagedby the internally threaded cup-shaped nutf22 freely extending into the opposite end of the bore 21, thereby permitting a lateral support for the last 16 for convenient operation thereon.

lVhen a shoe S as shown in Fig. 1 is mounted upon the last 16, the toe portion of the shoe and last are further braced and supported by the bracket arm 23 carrying a head 24 at its upper end for supporting the shoe, the lower end 25 of the bracketarm being received in the perpendicular opening 26 provided in the laterally projecting lug 27 carried by the block 9 as clearly shown in Figs. 1 and 4. The shoe S is further braced and anchored Yat the toe portion thereof on the bracket arm 23 by the belt or strap 28 having the looped portionfthereof overlapping and enclosing the toe portion of the shoe, the other end of the strap being associated with a key 29 carrying a rectangular eXtensionBO as shown in Figs. 1 and 7 fi`or reception in the rectan-gular socket 31 formed in the perpendicular post 2 as shown in Figs. 1 and 2. VThe laterally `projecting lug 27 carried by the block 9 is further provided with a horizontal rectangularopening v32 into which the pin: extension 31Lmay be received as shown by dotted linesl in Fig. 1.

From the above detailed description of the device, it is believed that the construction and operation thereof will at once be apparent, it being noted that theshoe jack as illustrated in Figs. 1 and 2'may` have the perpendicular post, section 2 removed therefrom to permit use of the jack while the operator is in a sitting position. The pivotal mounting of the head 5 upon each endV medium of the screw-bolt 11 formed integral portion 4 of the cross head 3 permits the desired adjustment of the block 9 that supports the shoe last, the block being rotatably adjustable upon the head 5 through the with the block and the nut 12 associated with the lower projecting end thereof asL shown Ain Fig, 5 The outer or upper ends of the blocks'9 are also 'constructed to provide for either a perpendicular or lateral support for thel shoe last as lshown in Figs.y 3 and 4, while the bracket arm 23 and-belt 28 main tain the shoe S rigidly positioned during operation thereon.
